We've been told that online and constant trimming is the default in

they can't service efficiently.

Win7 collects multiple TRIM ranges over time and batches them as single TRIMs
(as reported to me by an SSD vendor who traced it with a SATA analyzer,
  and who also apparently has "inside info").

I really hate to rely on this third party hearsay (from all sides), and
have implement TRIM support in qemu now.  I'll soon install win7 and
will check out the TRIM patters myself.

Excellent!
